Answer: (x - 2)^2 + (y + 3)^2 = 34

Step-by-step explanation:

The basic equation for a circle is

(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre of the circle

Using Pythagoras we can find r^2

r^2 = (2 - -1)^2 + (-3 - -8)^2

= 3^2 + 5^2

= 34

So the circle is (x - 2)^2 + (y - -3)^2 = 34

The Equation of Circle is (x -2)² + ( y + 3)² = 34.

The standard equation of a circle is given by: (x-h)² + (y-k)² = r². Where (h,k) is the coordinates of center of the circle and r is the radius.

We know the standard form of Equation of Circle

(x - a)² + (y - b)² = r²

where (a, b) is the Centre of the circle

Also, we have a  circle with a center at (2,-3) passes through the point (-1,-8).

Using Pythagoras theorem

r² = (2 - -1)² + (-3 - -8)²

= 3² + 5²

= 34

Thus, the Equation of Circle is (x -2)² + ( y + 3)² = 34.

32 ft

Step-by-step explanation:

Given data

Length= 8ft

Area= 64 f^2

Let us find the width

Area= Length*Width

64= 8* Width

Width= 64/8

Width= 8ft

Hence the perimeter= 2L+2W

P= 2*8+2*8

P= 16+16

Answer:

x = 24°, y = 53°

Step-by-step explanation:

An inscribed angle is half the measure of its intercepted arc.

arc EC = 2 × ∠ EDC = 2 × 78° = 156°

x = arc BE = 180° - arc EC = 180° - 156° = 24°

------------------------------------------------------------------

arc CD = 2 × CED = 2 × 41° = 82°

arc BD = 180° - arc CD = 180° - 82° = 98° , then

∠ BCD = [tex]\frac{1}{2}[/tex] × 98° = 49°

Then

y + 78° + 49° = 180° (sum of angles in triangle )

y + 127° = 180° ( subtract 127° from both sides )

y = 53°

Step-by-step explanation:

To find the slope of the side xy, we use the slope formula

we have the formula as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (-1,3)

(x2,y2) = (0,1)

m = (1-3)/(0 + 1) = -2/1 = -2

The distance between the two points will be 10 units.

A coordinate plane is a 2D plane created by the junction of the x-axis and y-axis, two perpendicular lines. A coordinate system in geometry is a way to use one or more integers or coordinates to determine the positions of the points.

Given points are (1,3) and (5,6). The distance between the points will be calculated as below:-

D = √ [ ( y₂ - y₁ )² + ( x₂ - x₁ )² ]

Substituting the given values, we get:

D = √((3 - (-3))² + (-4 - 4)²)

D = √(6² + (-8)²)

D = √(36 + 64)

D = √(100)

D = 10

Therefore, the distance between the two points (-3, 4) and (3, -4) is 10 units.

Answer:  ($3.50- 10% = 3.4)

Step-by-step explanation:

The final cost of milk is $ 3.36875

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

price of galloon of milk = $3.50

Discount  = 10%

tax = 6.25%

Now, price after discount

=3.5 x 0.10

= 0.35

and, after tax

=3.5 x 0. 0625

= 0.21875

Hence, final cost of milk = 3.5 -0.35  + 0.21875= $ 3.36875

Answer:

The expression is [tex]T(n) = 2*(3)^n[/tex]

Step-by-step explanation:

Geometric sequence:

In a geometric sequence, the quotient between consecutive terms is always the same.

The general rule of an geometric sequence is given by:

[tex]T(n) = T(0)(q)^n[/tex]

In which T(0) is the initial amount and q is the quotient.

During the first 4 years after the fire, she records 2, 6, 18, and 54 trees.

First term is 2, so [tex]T(0) = 2[/tex].

Quotient is [tex]q = \frac{54}{18} = \frac{18}{6} = \frac{6}{2} = 3[/tex]

So

[tex]T(n) = T(0)(q)^n[/tex]

[tex]T(n) = 2*(3)^n[/tex]

The expression is [tex]T(n) = 2*(3)^n[/tex]

Answer:

5.88 x 1012

Step-by-step explanation:

To write each of these numbers in decimal notation, you move the decimal point the same number of places as the exponent. If the exponent is positive, move the decimal point to the right. If the exponent is negative, move the decimal point to the left. If you start at the decimal of 5.88 and move it 12 spaces to the right, then you get 5,880,000,000,000 miles.

The number represented in scientific notation is 5.88×1013.

It is the way of writing a large number between 1 to 10 with a power of 10.

We have,

5,880,000,000,000 miles is equivalent to 1 light year.

We can convert this number to scientific notation by moving the decimal point 13 places to the left

(because there are 13 zeros in 5,880,000,000,000) and multiplying by 10 raised to the 13th power:

So,

= 5,880,000,000,000

= 5.88 × 10¹³

Therefore,

The number represented in scientific notation is 5.88×1013.

Population of fish in 2010 = 1,646 fish (Approx.)

Step-by-step explanation:

Given:

Population of fish in 2002 = 2100 fish

Decrease rate = 3% per year

Find:

Population of fish in 2010

Computation:

Number of year = 2010 - 2002
